asterisk: Drop the very old version from meta-telephony

We used asterisk to be able to speak SIP with the outside. LCR
has gained this capability in the past and we haven't used asterisk
in more than two years.

Asterisk doesn't seem to compile with master/dizzy and there is
little point in figuring out why.
